CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation in part of U.S. patent applicationSer. No. 16/874,315 filed with the United States Patent and TrademarkOffice on May 14, 2020 which in turn claims the benefit of U.S.Provisional Patent Application No. 62/847,679 which was filed with theUnited States Patent and Trademark Office on May 14, 2019, the entirecontents of each of which is herein incorporated by reference.

BACKGROUND 1. Field

Example embodiments relate to a system configured to convert a liquid toa fog and disperse the fog. The fog may include, but is not required toinclude, an insecticide, a disinfectant, and/or an antimicrobial agent.In example embodiments the fog may be applied over a relatively largearea or a relatively small area.

2. Description of the Related Art

Often times large areas of land are infested by large numbers ofmosquitos. Many times, ground based foggers are used to introduce a foghaving an insecticide therein to kill the mosquitos. Most conventionalfoggers convert a liquid to a fog by applying energy to the liquid. Thisis generally done in several ways. Some, for example, use an air blastto transfer energy to the liquid. Most of these systems use an 18horsepower engine and generally convert about 15 ounces of liquid to fogin one minute. Other systems use rotary atomizers. These systemsgenerally use a porous material which is spun at around 30,000 RPMs. Inthese systems liquid is injected into the center. As the liquid is spunit separates into a fog. Systems using rotary atomizers generallyconvert about 15 ounces of liquid to fog in one minute. Other systemspass pressurized water through a nozzle at around 5,000 to 7,000 psi.Most fogging equipment is relatively expensive and difficult to use. Assuch, there is a need for a fogging apparatus which can generate a largevolume of fog which is in expensive and easy to use.

SUMMARY

In general, example embodiments are drawn to system configured togenerate and disperse a fog. The system may include a reservoir forholding a liquid, a pump to pump the liquid through the system, a nozzleto convert the liquid to a fog, and various safety features, forexample, a level cutoff switch, a safety relief valve, and a highpressure switch. The system may be portable and may be supported on avehicle, for example, a car, a truck, or a cart. The system may beconfigured so that the volume of fog dispersed by the system isdependent on the speed the vehicle travels. In example embodiments thenozzle may resemble a fish hook like structure. One side of the fishhook like structure is attached to the side of the nozzle. The nozzlealso includes a small flat surface positioned directly in front of thenozzle opening. So, the nozzle creates a jet out of the liquid.Immediately after leaving the nozzle opening the jet hits the surfaceand shatters into a fog. The inventor has found this to be an extremelyefficient method of applying energy to a liquid. In example embodiments,the nozzle has the ability to convert 2-20 oz/min which may operateunder a pressure of 3,000 psi or less. The nozzle may be part of amanifold which may be configured to support several nozzles having anidentical configuration. An example embodiment of the inventor's systemis capable of converting 64 oz/min. The amount that may be converted canincrease by selecting the proper pump and using additional nozzles.

Generally, example embodimentsrelate to a system capable of converting a liquid to a fog.

FIG. 1 is a view of a system 1000 configured to convert a liquid to afog and dispense the fog to the environment. The liquid may includechemicals, such as insecticides, to kill various pests, for example,mosquitos and/or flies, that may be in the environment.

In one nonlimiting example embodiment, the system 1000 may bemounted on a back of a truck. Thus, the system 1000 may be mobile so thesystem 1000 may be moved to cover a fairly large area of land. In analternative embodiment, the system 1000 may be mounted on a push cartand the pushcart may be configured to be pushed by a person eitherinside or outside of a building. This latter embodiment may beespecially useful in decontaminating a building. In yet anotherembodiment, the system 1000 may be placed in a single location andoperated from that location without being moved.

In its most basic form, the system 1000 includes a reservoir 100 forholding the liquid. The liquid, as mentioned above, may includechemicals that act as insecticides, however, the invention is notlimited thereto. For example, the system 1000 may hold other chemicalssuch as, but not limited to, antimicrobial agents, herbicides,pesticides, and/or fertilizers. The reservoir 100 may hold severalgallons of liquid, for example, 50 gallons, though the amount of liquidheld is not critical to the invention. In practice, the system 1000 maycontain multiple reservoirs for different chemicals or flushing. Whileit was described above that the reservoir 100 may hold 50 gallons ofliquid, it may, alternatively, hold more or less than 50 gallons ofliquid. Reservoir 100, for example, may hold as little as 1 gallon ofliquid.

In example embodiments a pump 200 may be used to pump the liquid throughthe system 1000. In the nonlimiting example of FIG. 1 , the pump 200 maybe driven by an electric or internal combustion motor 210, for example,a 12 VDC motor, though the example is not limited thereto. For example,depending on the application a larger or smaller motor may be used. Inexample embodiments the motor 200 be controlled by a dial 220 which maybe part of a rheostat, or some other motor controller, to control thespeed of the motor 210. Thus, an operator may increase or decrease thespeed of the motor 210 by adjusting the dial 220. Of course, as oneskilled in the art would understand, the speed at which the pump 200operates is affected by the speed of the motor 210. Thus, a user cancontrol the speed at which the pump 200 operates by controlling thespeed of the motor 210 which may be controlled by the operation of thedial 220.

In example embodiments, a first conduit 10 may transfer the liquid tofrom the reservoir 100 to the pump 200. The first conduit 10 may, forexample, resemble a flexible hose. The flexible hose may be made from aplastic or other similar material appropriate for the chemical beingused. In another embodiment the first conduit 10 is a nonflexibleconduit and may resemble a metallic pipe or tube appropriate for thechemical being used. In another embodiment the first conduit 10 is ahydraulic hose. Regardless, the conduit 10 is configured to allow theliquid to flow from the reservoir 100 to the pump 200.

In example embodiments a second conduit 20 may transfer the liquid fromthe pump 200 to a nozzle 300. The nozzle 300 may convert the liquid to afog for dispersal by the system 1000. The nozzle 300, for example, maybe an impact nozzle.

In example embodiments the rate at which the liquid flows through thesystem 1000 is controlled by the speed of the motor 210 and pump 200. Asthe motor 210 and pump 200 speed increases, the flow rate of the liquidincreases. As the nozzle 300 is too small for free flow of the liquid,pressure develops and increases as the amount of fluid sent to itincreases. In example embodiments, the pressure in the system 1000 maybe controlled by a user by controlling the dial 220. As the dial is“turned up” the pressure in the system 1000 increases. As the dial is“turned down” the pressure in the system 1000 decreases. A user,therefore, can set the desired pressure in the system 1000 to a desiredlevel by operating the dial 220. Pressure directly correlates with flow.As pressure increases and decreases flow increases and decreasesaccordingly.

In example embodiments, the system 1000 may be vehicle mounted in orderto treat an area for a certain type of pest, for example, mosquitos. Incertain circumstances it may be desired to control the amount of fogproduced by the apparatus 1000 based on the speed at which the vehicleis driven. The faster the vehicle is driven the greater the speed atwhich the pump 200 may be driven. In order to allow for the properproduction of fog the system 1000 may include a variable flow controller230. The variable flow controller 230 may control the motor 210 speedbased on the speed of the vehicle on which the system 1000 is mounted.For example, as the speed of the vehicle increases the variable flowcontroller 230 would increase the speed at which the motor 210 isdriven. Similarly, as the speed of the vehicle decreases, the variableflow controller 230 would decrease the speed at which the motor 210 isdriven. This example, of course, is not meant to limit the invention.For example, in another embodiment, the valve 500 may be controlledbased on a speed of the vehicle. For example, the faster the vehicledrives the more closed the valve 500 may be to increase pressure in thesystem and produce more fog. Alternatively, as the vehicle is drivenslower the valve 500 may be more open to reduce pressure in the systemto produce less fog. Thus, in this latter embodiment, the motor may runat a constant speed while the vehicle is moving and the amount of fogproduced is controlled by controlling the valve 500.

The variable flow controller 230 and/or valve 500 may determine thespeed of the truck in various ways. In a first nonlimiting exampleembodiment, the system 1000 may include a GPS device 400 which gathersGPS data and sends the GPS data to the variable flow controller 230and/or valve 500 either wirelessly or over a wire and the variable flowcontroller 230 and/or valve 500 may use the GPS data to determine thespeed at which the truck is moving. In other words, the variable flowcontroller 230 and/or valve 500 may have circuitry with electricalcomponents configured to determine how fast the system 1000 is travelingbased on the GPS data. In another embodiment, the vehicle may beequipped with a blue tooth device which may allow data related to speedof the vehicle to be sent to the variable flow controller 230 and/orvalve 500 from the vehicle's onboard computer. In yet anotherembodiment, the system may include an electronic controller connected tothe cloud and the electronic controller may receive location informationfrom the cloud which may be used by the electronic controller todetermine the speed at which the system 1000 is driven and thiselectronic controller may control system 1000 accordingly. In yetanother embodiment, the system 1000 may be Bluetooth enabled and mayconnect to an application of a smart device, for example, a smart phoneor a tablet, and the Bluetooth device may include an app which receiveslocation information and the smart device may operatively control thespeed at which the motor 210 operates and/or controls how open the valve500 should be.

In example embodiments, pressure in the system 1000 may controlled bythe pump 200 and motor 210 speed. In the particular embodiments shown inthis application, pressure on the pressure side of the pump 200 isgenerally limited to be in a range of 700 psi to 3000 psi, and morepreferably between 1000 psi and 2000 psi, and even more preferablybetween 1000 psi and 1500 psi. However, there is a risk, especially witha clogged nozzle 300, that pressure can increase in an uncontrolledmanner which may exceed pressures beyond which system 1000 can safelyaccommodate. Another potential hazard could occur if the reservoir 100runs out of liquid. Therefore, system 1000 may further include one ormore safety features. For example, in one nonlimiting exampleembodiment, system 1000 includes a level cutoff switch 110. The levelcutoff switch 110 may sense a level of liquid within the reservoir 100and may stop the system 1000 from functioning in the event the level ofliquid in the reservoir 100 falls below a preset value. This preventsthe pump 200 from operating in a dry state. An example of the levelcutoff switch 110 is a low level cut-off switch. In addition, the system1000 may include a High Pressure Switch 240. The High Pressure switch240 may sense pressure in the system 1000, for example, pressure in thesecond conduit 20, and may stop the system 1000 from functioning in theevent the pressure in the second conduit 20 exceeds a preset value.Though the embodiment of FIG. 1 shows the high pressure switch 240 asbeing in a position to sense of pressure of the system 1000 by sensing apressure of the second conduit 20, it may alternatively sense a pressurein a third conduit 30 instead. In fact, the inventive concepts cover anyembodiment where the high pressure switch 240 senses a pressure on apressure side of the pump 200. The system 1000 may include additionalsafety systems. For example, the system 1000 may further include a thirdconduit 30 which branches off the second conduit 20. The third conduit30 may direct the pressurized liquid from the pump 200 to a valve 500,which may be a safety relief valve, which may open when the pressure inthe third conduit 30 exceeds a set value of the pressure relief valve500. When the pressure in the third conduit 30 exceeds the safety reliefvalve's 500 set pressure, the safety relief valve 500 opens so that atleast some of the liquid pumped by the pump 200 is returned to thereservoir 100 via a fourth conduit 40. It is understood that the valve500 may operate as a safety relief valve and may also be controllable tocontrol pressure in system 1000. In example embodiment, valve 500 mayrepresent two valves, on as a traditional safety relief valve and theother as a controllable valve which is configured to control an amountof liquid passing through the third conduit 30 or the fourth conduit 40.

In example embodiments the system 1000 may include an electrical systemto control the motor 210. The electrical system may route power from apower source 600, for example, a battery or an AC power source, firstthrough the level cutoff switch 110, then to the high pressure switch240 before being routed to the motor 210. Thus, the motor 210 won'toperate in the event the reservoir 100 is not filled with enough liquid.In the event the reservoir 100 is filled to the proper level power willflow next to the high pressure switch 240 which detects pressure withinthe system 1000. If the pressure is above a pre-set value, the highpressure switch 240 will prevent power from flowing to the motor 210.FIG. 5 illustrates a couple of nonlimiting examples of relays usable inexample embodiments. The top nonlimiting example shows a relayconfigured as a normally closed relay whereas the bottom example shows arelay configured as a normally open relay. In either case, power from apower source, for example, a 12 Volt battery, may be attached to therelay at 7 and 8 and the relays may control power to a motor controllerbased on whether a fault is detected. For example, if either of pressuresensor detects pressure on the pressure side of the pump in system 1000is too high or if the low level switch indicates there is not enoughliquid in the reservoir, then power to the motor controller may be shutoff and/or power within the system is disrupted.

In example embodiments, the system 1000 may further include a fan 700which may, in one embodiment, sit behind the nozzle 300 to push anddisperse the fog and, in another embodiment, may be placed in front ofthe nozzle 300 in order to draw the fog out of the nozzle and blow thefog into the environment. In either embodiment, the fan 700 may be anoscillating fan to blow fog in many directions. Of course, in otherembodiments, the fan 700 may be omitted. In one embodiment the fan 700may be configured to turn on when the system 1000 is activated or may,in another embodiment, be operated independent of when system 1000 ispowered up. In one embodiment, the fan 700 may have a support tube whichmay support the nozzle 300.

In example embodiments the set pressure of the safety relief valve maybe lower than the pre-set value associated with the high pressure switch240. This may prevent the system from ever reaching an unsafe pressurelevel.

As one skilled in the art would readily appreciate, the pressure insystem 1000 is controlled by the speed of the pump 200. If the nozzle300 opening is constant, the faster the pump 200 operates the greaterthe pressure. If extra nozzles are added (via a nozzle manifold) thepump 200 must be operated faster to build pressure to a desired range.By adding and subtracting nozzles via the manifold and using smaller orlarger pumps, virtually an unlimited amount of fog can be produced.This, however, is not intended to limit example embodiments. Forexample, safety relief valve 500 may be configured to controllably openor close and may be used to control a pressure in the system 1000. Forexample, the pump 200 may be operated at a constant speed and a pressureof the system 1000 on a pressure side of the pump 200 may be controlledby controlling the opening and closing of the valve 500. Opening thevalve 500 reduces the pressure in the system whereas closing the valve500 increases the pressure. Thus, in this latter embodiment, pressure inthe system 1000 may be controlled by controlling the opening and/orclosing of valve 500 rather than by varying the speed of the pump 200.

FIG. 2 is a view of the nozzle 300. As shown in FIG. 2 , the nozzle 300includes a hollow J-shaped structure 310 having an outlet 312 thatdirects the pressurized liquid to a flat surface 314 where the liquidshatters and turns into a fog. The nozzle 300 has an ability to convert2 to 20 oz of liquid to fog per minute while being kept under a pressureof under 3000 psi. Though not shown in the figures, a manifold may beprovided which may include one or more nozzles 300. The additionalnozzles 300 translates into greater fog production. It should be notedthat the inventor has found that rapidly moving liquid being directedonto a surface, for example, a flat surface, is surprisingly efficientat converting the liquid to fog.

In example embodiments the system 1000 may be vehicle mounted, but thesystem may also be used in a stationary setting. For example, the system1000 may be placed on a truck or a pushcart or may alternatively beplaced in a designated spot in a building to produce fog. The system1000 may be used to fumigate an outdoor area, but may also be used tofumigate and indoor area as well. The system may be controlled tofunction as a ULV fogger configured to generate fog having sizes of 30microns or less.

FIG. 6 is another example of a system 1000 configured to generate anddeliver a fog in accordance with example embodiments. The system 1000 ofFIG. 6 is similar to the previously described systems, as such, adetailed description thereof is omitted for the sake of brevity.However, it should be noted that in FIG. 6 , the valve 500, which may bea safety relief valve, an unloader valve, or a pressure regulator valve,may be configured to recirculate pumped liquid back to the pump 200 viaa conduit 40. As in the other embodiments, the valve 500 may preventexcessive pressure, for example, pressure above 3000 psi, from buildingup in the system 1000 of FIG. 6 on the pressure side of the pump 200.For example, if the nozzle 300 gets plugged pressure in the secondconduit 20 may build up. As the pressure builds the pressure in thethird conduit 30 likewise rises as does the pressure in the valve 500.When the pressure exerted on the valve 500 exceeds its set point thevalve 500 opens allowing for liquid to flow through the third conduit30, through the valve 500, through the fourth conduit 400 and back tothe pump 200. For example, the fourth conduit 400 may branch into thefirst conduit 10 or may independently attach to the pump 200. Therecirculation system of FIG. 6 (which may be the third conduit, thevalve 500, and the fourth conduit 40) may prevent pressure from buildingup on the pressure side of the pump 200 from exceeding a desired orpreset level. In one nonlimiting example embodiment, the valve 500 isconfigured to recirculate some or all of the liquid pumped by the pump200 necessary to maintain or limit the system 1000 to a particularpressure. For example, the nozzle 300 of FIG. 6 may be part of amanifold which may be configured to support several nozzles. In thisembodiment one or more of the several nozzles may be plugged and thusonly a portion of the liquid pumped by the pump 200 to the nozzle 300need be diverted in the recirculation system to maintain a desiredpressure. As an alternative to the embodiment of FIG. 6 , pump 200 maybe configured with an integrated valve with an internal return forrecirculation, thus, the valve 500 may be omitted in its entirety.

Example embodiments of the invention have been described in anillustrative manner. It is to be understood that the terminology thathas been used is intended to be in the nature of words of descriptionrather than of limitation.
